"Neonicotinoid insecticides" are a type of chemicals used to kill insects that harm crops. They work by attacking the nervous system of insects.

Many
blame neonicotinoid insecticides — a new type of insecticide related to nicotine that attacks the nervous system of the insects and is deemed less toxic than organophosphates — although not everyone agrees.
In 2013, the European Commission acted to protect bees by restricting the use of three
neonicotinoid insecticides within the twenty - eight countries of the European Union.
Although that began prior to 2006, what did almost precisely coincide with the initial outbreaks of CCD was the emergence of widespread commercial treatment of corn seed
with neonicotinoid insecticides.

The research is the first time scientists have looked into how both species respond to field - realistic - levels of
the neonicotinoid insecticide «clothianidin» which was banned for use on flowering crops by the European Union in 2013.
I am very pleased that a sound scientific risk approach has been taken by the European Union in its decision not to suspend use of
neonicotinoid insecticides, as proposed last year (7 April 2012, p 18).
Neonicotinoid insecticides are neurotoxic and used around the world on broad varieties of crops, including common fruits and vegetables, through spray, soil and seed applications.
The researchers found that bumblebees exposed to a realistic level of
a neonicotinoid insecticide (thiamethoxam) collected more pollen but took longer to do so than control bees.
More than 70 per cent had been treated with
neonicotinoid insecticides, which are strongly suspected of being bad for bees.
